Large excavator 9020XPC

crawlermining and quarryingfor mining

Overview
The P&H 9020XPC dragline is engineered for continuous heavy-duty material handling in large open-pit operations. Available with multiple boom lengths and bucket capacities, the machine combines a high-capacity tub, four-chord boom construction and a Centurion electronics platform to support reliable, efficient production and simplified monitoring.

Key features

• Ultra-strong tub distributes loads evenly for outstanding reliability
• A-frame engineered to effectively manage load forces
• Four-chord boom provides structural integrity to operate in tough conditions
• Electronics platform (Centurion control system) to help operators perform at peak efficiency and monitor dragline operation
• Highly engineered boom and A-frame deliver stability, excellent visibility of boom point sheaves and balanced axial working loads
• Designed with user input to improve safety, delivery, maintenance and inspection activities
• Comprehensive service support to lower total cost of ownership and optimize production

Design and construction highlights

• Tub engineered for long life and low maintenance; verti-shield welding joins on all intersection plates with one continuous weld resulting in minimal distortion
• Four wide-flanged chords with line pipe lacing for boom construction; boom material: HSLA
• Constant Contact Style fairlead and large-diameter sheaves for hoist/drag systems
